The term is probably not new at all, I have probably seen it before, but sometimes I suppose we all need to be in the right frame of mind to be receptive to certain things at certain times.

What I like about the term is that it probably won't allow people who are ignorant of blogging to dwell too much on pre-conceived ideas of what blogging can be about.

Anyway, the article I read (The growing market for blogs, James Cherkoff, BBC News: Technology) tries to breakdown the image of blogs being, "akin to a ranting madman on the corner". Instead, people are encouraged to see blogging, potentially anyway, as, "massive intertwining communities" and "have the vibrancy and passion of an enormous street market."
